To all wh'o'lt;itmaycoaccmf I 7 Be itknownthatL'Jo N L.' ConoeRnN, a citiaen of the'Un'ited Eltatet, and a resident of thecity"of"Oincinnatitln the county of Hamilton 'and' Sta'te' of Ohio,l have lnvented certainhew and'useful Improvements 1n Electric Ilamps, of'which the following is a full,'clear, and exact descript1on,'reference being had to the accompanying drawlngs, forming part'of this specification.

My invention ;relates to hand lamps en-p ergized-by anelec'tric battery of the type which employ the standard, s zeddry battery of common use. a lit has as its object-the providing of a simple and' convenient container for the battery, and asimpleancl convenient mountmg means for the light, thelatter to be so arranged-that la-turning of the reflector caslng will turn'onlan'dofl the lightl These objects and various other advantages asr-will be noted-I accompllsh'by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

"In the drawings, Figure 1 is a side elevation of the lamp partly broken away to show the dry cell in place. Fig. 2 is a top plan view of the container broken away to show the method of securing the lid to the can, bymeans of the handle. Figs. 3, 4 and 5 are perspective views of the electric contact plug, the lamp socket retaining plate and the gasket for the latter respectively. Fig. 6 is ahorizontal section through the electric contact plug; Fig. 7 is a perspective view of the electric bulb and its base. Fig. 8 is a side elevation of the lamp in. place in the lid of the can or container, with said lid and part of the lamp socket broken away.

The can or container 1 has a handle 2 suitably secured to the rear thereof and hav-' ing a peripheral bead 3 against which the lid or top 4 abuts when in place. The lid 4 has two apertures and the can 1 has apertures to register therewith (Fig. 2), said apertures being adapted to receive the ends 5, 5', of a bail 6. By this means the can and its lid are held together, but may be easily-separated by means of springing the ends-of the bail out of the apertures above noted. The can is of the proper size to contain a standard sized dry battery 7 The socket 8 of the reflector 9 is inserted through a hole in the lid, the top edge of anaemic-name;

"The electric bulb 10 is mounted in the socket bymeans of pins 11 on its base 12. I This base is inserted from the front into the socket of the lamp casing and the plns caught in the slots 13 in the socket portion as is readily understood. Located at the end of the base 12are the contact points 14,

i 14 (Fig 7).

A plate of insulated material 15, spaced 'away from the top of the can by a plate 16 v (Fig. 3)] is provided, the conducting wires V 1 17, 17 from the two poles of the battery be5 =ing led through apertures 18, 18 in this plate and secured by small screws 19 in the contact plug 20'(Figs. 3 and6). This plug has the spring contact pin's2'1,said pins being adapted when theparts are assembled to bear on the end of the lamp base 12, and in certain positions thereof t contact with the contact points 14, 14 thereof."

Mounted on the face of the p1ate-15 is a clip 22, faced with an insulating piece 23 (Figs. 4 and 5). The plate 'an'd the clip together with the spacing and insulating members mentioned are all secured to the top of the can by means of a pair of small bolts 24. The clip has a cut formed in its upper surface and a tongue 25 turned down from said out. The lamp socket is retained under said clip when the parts are assembled by means of this tongue engaging in a slot 26. formed in the socket. This slot is of suflicient width to permit of the lamp socket being turned within the clip. The electric contact plug lid within the socket, when assembledtiand' the tongue extending down through the slot therein, engages a hole 27 formed in theplug. The lamp is then operated to turn the current from the battery on and off from the lamp bulb, by means of revolving the reflector. When this is done a partial turn of the lamp will revolve the contact points 14, with relation to the spring pins 21, 21, causing a contact to be made. The plug 20 will not turn because it is held by the tongue engaging the hole 27 therein. The reflector may be turned because the tongue slides in the slot 26 therein.

From the construction now described, it is plam that the lamp and all its connections are secured to the easily removable top of the can, and that when it is desired to take off the 11d, the bail is first removed and the cell will fill it up entirely with its carbon terminal 28 abutting against the top of the lid. One single clip sufiices to hold all lamp parts to the top of the lid, and a simple and effective means for energizing the lamp by means of revolving it, is provided.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is

1. In an electric lamp, having a container portion and a lid portion, a lamp socket, a light bulb mounted in said socket, a battery in the container, a contact plug mounted in said socket electrically connected to said battery, and a clip secured to the lid for mounting the lamp soHret, and means on the cllip for holding in fixed position the electric p ug.

2. In an electric lamp, having a container portion and a'lid portion, a lamp socket, a light bulb mounted in said socket, a battery in the container, a contact plug mounted in ing its base in said socket electrically connected to said batte'ry, and a clip secured to the lid for engaging over the lamp socket, a tongue on the clip for engaging a slot in said socket, and means whereby said tongue engages said plug, to hold it in fixed position.

3. In an electric lamp, having a container portion and a lid portion, a lamp socket, alight bulb mounted in' said socket, a battery in the container,'a contact plug mounted in said socket electrically conneeted to said battery, having spring pins to contact with the base of the light bulb, and a clip secured to the lid for engaging over the lamp socket,

a tongue on the clip for engaging a slot in said socket, and means whereby said tongue engages said plug, to hold it in fixed position.

4. In an electric lamp, a container portion and a lid portion, a socket, a light bulb havsaid socket, means for mounting the socket on the lid so as to permit a partial movement thereof, a contact plug, and means for mounting the contact plug in a fixed position on the lid Sothat it is in contact with the base of the light bulb.
